rate of data aquisition vs rate of recording data

Hi everyone,

Im pretty new to Labview and im stuck with this issue:

I'm attempting to build a VI that reads temps from my NI 9213 at at rate of about 1 sample/sec and I was going to record the data using the write to measurement file however recording at that same rate is too much data, I would like to instead record about once every 30 seconds. Does anyone have a solution?

Thanks.
